The prison of Harrowstone has long been an empty ruin, haunted by more than the mysteries and memories of a tragic past. When invaded by the death-crazed servants of the Whispering Way, a cult dedicated to the service of the infamous lich Tar-Baphon, Harrowstone’s long-quiet population of ghostly inmates rises in an undead revolt. Brought together by the death of an ally, the heroes unite to save the residents of a tormented town and lay the spirits of Harrowstone to rest. Yet doing so brings new life to a long-forgotten mystery, where avenging an innocent’s murder means putting an end to some of Ustalav’s most infamous criminals for a second time.
